The contribution of the liver and kidney to the optical isomerization of (R)-(-)-2-phenylpropionic acid (hydratropic acid (HTA] was examined by iv injection of racemic HTA (20 mg/kg) to nephrectomized and bile duct-ligated rats (NEBL-rats), eviscerated rats with nonfunctioning livers (EVIS-rats)

Chemically reactive species formed from the metabolism of carboxylic acid-containing compounds have been proposed as mediators of their toxic side-effects. Two alternative metabolic pathways known to be involved in the generation of reactive acylating metabolites of carboxylic acids are acyl

The significance of disturbances of lipid metabolism caused by xenobiotic acyl-CoAs as possible causes of peroxisomal proliferation has been studied with the enantiomers of 2-phenylpropionic acid (2-PPA), the (R)-enantiomer of which is converted to the acyl-CoA in rats while its

The usefulness of thin-layer chromatography (TLC) as an efficient measuring technique in the studies of oscillatory trans-enantiomerization of profens from the S to the R configuration (and vice versa) during their storage as 70% ethanol solutions is demonstrated in the

Previous investigations have described the development of nongrowing suspensions of Verticillium lecanii as a microbial model of the mammalian chiral inversion of the 2-arylpropionic acids (2-APAs). Mechanistic studies in mammals have shown that inversion involves loss of the alpha-methine proton
